Abstract: Adjusting the structure of agricultural industry and promoting the development of industrial convergence is an important content of village economic reform during the 13th five-year plan. In this thesis, it uses the method of grey correlative analysis to analyze the correlation between the industrial output value and gross output value of agriculture from 2006 to 2013 of Qujing. The results show that the sorting of grey relative theory is forestry, services in support of farming, forestry, animal husbandry and fishery, farming, animal husbandry, fishery. It implies that forestry and services in support of farming, forestry, animal husbandry and fisher make up a smaller part, but they have a great gray correlation degree with the total of agricultural output value. Farming and animal husbandry have a high proportion, while the Grey Relational Degree is relatively weaker. The proportion and gray correlation degree of fishery are smaller. Therefore, it integrates the practice of Qujing and puts forward suggestion that promoting industry structure adjustment in agriculture and developing advantage industries.
